【摘要】：本试验研究了不同褐壳蛋鸡品种在相同的饲养管理条件下养殖效果,以比较出适宜饲养的褐壳蛋鸡品种。本试验分三部分进行,第一部分:育雏期比较。在育雏期选择海兰褐、京红、伊莎褐、罗曼褐、海赛克斯褐五个品种,相同的饲养管理条件下进行饲养。结果表明:不同品种种蛋入孵时的蛋重,经方差分析,没有显著差异。不同品种雏鸡初生重差异极显著,海赛克斯褐和伊莎褐初生重与其它品种间差异极显著(P0.01),罗曼褐与京红之间初生重差异极显著(P0.01)。除海兰褐与罗曼褐之间初生重差异不显著(P0.05),其余品种的初生重均存在显著差异(P0.05)。育雏期不同蛋鸡品种增重情况存在差异,2周龄时罗曼褐增重最快比伊莎褐体重高7.6%,差异极显著(P0.01),同时比京红体重高5.3%,差异显著(P0.05),其余的两个品种海兰褐和海赛克斯褐体重差异不显著(P0.05),生长至8周龄时依然是罗曼褐蛋鸡的生长速度最快,此时罗曼褐比伊莎褐体重高6.4%,差异极显著(P0.01),比海赛克斯褐体重高4.6%,差异显著(P0.05);海兰褐比伊莎褐体重高4.3%,也存在差异显著(P0.05)。育雏期海兰褐、罗曼褐高于其它品种,其次为京红、海赛克斯褐、伊莎褐。第二部分:育成期比较。育成期不同品种蛋鸡从育雏舍转移到三阶梯笼养式蛋鸡舍,5个不同品种蛋鸡在相同饲养管理条件下进行饲养。结果表明:不同品种蛋鸡在不同周龄体重增长情况存在差异。8周龄时,伊莎褐与其它各品种间存在差异(P0.05)。11周龄京红和海赛克斯褐品种间无差异(P0.05)与其它品种间存在差异。19周龄时京红与海兰褐、海赛克斯褐差异不显著(P0.05),海兰褐和伊莎褐之间差异不显著(P0.05),罗曼褐品种此时与其它品种间的体重存在差异显著(P0.05)。不同品种蛋鸡生长模型的比较,对于海兰褐蛋鸡来说,Gompertz曲线模型的拟合度最高,拟合效果最好。适合做生长曲线估计,而不同品种蛋鸡的拐点体重、拐点周龄和最大增重周期也不相同,其中,罗曼褐的拐点体重最大为923.845g,罗曼褐和京红的拐点周龄最大为11.119,伊莎褐的最大增重周期为3.334。育成期海兰褐发育高于其它品种,依次为罗曼褐、京红、伊莎褐、海赛克斯褐。第三部分:产蛋期比较。产蛋期5个不同品种蛋鸡在相同的饲养管理条件下饲养。结果表明:25周龄海赛克斯褐体重与其它品种间存在极显著的差异(P0.01)。不同品种鸡蛋横径与蛋形指数和蛋重呈极显著性正相关(P0.01),京红蛋形指数与蛋重呈极显著性正相关(P0.01),其余的呈不显著相关。31周龄时依然是海赛克斯褐与其它品种间不存在差异显著,海兰褐与京红和伊莎褐与罗曼褐间存在差异显著(P0.05)。蛋形指数上京红与海兰褐、伊莎褐、罗曼褐间差异不显著,而与海赛克斯褐差异显著(P0.05),海兰褐、罗曼褐与伊莎褐、海赛克斯褐差异极显著(P0.01)。蛋壳强度罗曼褐与其它品种差异极显著(P0.01)。哈氏单位海赛克斯褐与其它品种间存在差异极显著(P0.01)。在产蛋高峰的时候,海兰褐高于其它4个品种,依次为罗曼褐、伊莎褐、京红、海赛克斯褐。25周龄至43周龄海兰褐比罗曼褐、伊莎褐、京红、海赛克斯褐的产蛋率分别高0.5%、0.7%、0.75%、0.9%;海兰褐蛋鸡的产蛋量高,料蛋比海兰褐2.08:1、伊莎褐2.18:1、罗曼褐2.2:1、海赛克斯褐2.3:1、京红2.4:1。本次研究,认为海兰褐蛋鸡不失为理想的蛋鸡品种,此可供石家庄地区广大褐壳蛋鸡饲养者参考,也可为养鸡业的发展提供依据。
[Abstract]:This experiment studied the effect of different brown shell layers under the same feeding and management conditions, in order to compare the suitable breeds of brown shell and laying hens. The experiment was divided into three parts. The first part was divided into three parts: the first part: the brooding period. In the brooding period, five varieties of brown, Jinghong, ISA Brown, Luo Man brown, and sea race Brown were selected, and the same feeding management article was made. The results showed that there was no significant difference between the egg weight of different varieties of eggs and the variance analysis. The difference of the primary weight of different breeds was very significant, and the difference of the primary weight of the brown and isa Browns with the other varieties was very significant (P0.01), and the difference of the primary weight between the Roman Brown and the Beijing Red was very significant (P0.01). There was no significant difference in the primary weight difference (P0.05) among the other varieties (P0.05). The weight gain of different layers in the brooding period was different. When 2 weeks old, the weight gain of Roman Brown was 7.6% higher than that of ESA brown. The difference was very significant (P0.01), and the difference was significant (P0.05), and the other two varieties were significantly higher than that of Beijing Red (P0.01). There was no significant difference in brown and sea browning weight (P0.05). When the growth was 8 weeks old, the growth rate of Luo Manhe was the fastest. At this time, the Roma browning Brown weight was 6.4%, the difference was very significant (P0.01), and the difference was 4.6% higher than that of the brownish Brown weight (P0.05), and the brown brown brown body weight was 4.3%, and the difference was significant (P0.05 In the period of brooding, the Roman Brown is higher than other varieties, followed by Beijing Red, sea Sax brown, isaba brown. The second part: the breeding period is compared. The different breed layers are transferred from brooding house to three staircase caged chicken house, and 5 different kinds of laying hens are kept under the same feeding management conditions. The results show that the different kinds of laying hens are not in the same breeding condition. There was a difference between.8 weeks and other varieties (P0.05), there was no difference (P0.05) between.11 Zhou Jinghong and the other varieties (P0.05), there was no difference between Beijing Red and sea blue at the age of.19, and the difference was not significant (P0.05), and there was no significant difference between the browning brown and isa browning. (P0.05) there was a significant difference in the weight between the Roman Brown varieties at this time and the other varieties (P0.05). The comparison of the growth models of different kinds of laying hens was the best fit for the Gompertz curve model and the best fitting effect. It was suitable to estimate the growth curve, and the turning point of the different kinds of laying hens, the turning point of the week and the maximum increase. The heavy cycle is not the same, of which the maximum weight of the turning point of Roman Brown is 923.845g, the maximum of the turning point of Luo Manhe and Jinghong is 11.119, and the maximum weight gain period of isaba Brown is higher than that of other varieties in the period of 3.334. breeding, which are Roma Brown, Beijing Red, isesa brown, and sea Sax brown. The third part: the egg production period is compared. The laying period is 5 different periods. The same breed was kept under the same feeding management conditions. The results showed that there was a very significant difference between the 25 weeks' Sykes's Brown weight and other varieties (P0.01). The horizontal diameter of eggs was significantly positively correlated with egg shape index and egg weight (P0.01), and the number of Jinghong egg shape was significantly positively correlated with the egg weight (P0.01). There is no significant difference between the lignin brown and the other varieties when the.31 weeks of age are not significant. The difference between the brown and Beijing Red and the ISA Brown and the Roman Brown is significant (P0.05). The egg shape index is not significantly different between Beijing and Hai Lan, ISA Brown and Roman Brown, but the difference is significant with the sea Sykes Brown (P0.05), the sea blue brown, Luo Manhe and Ishaeas brown and sea Sax Brown difference is very significant (P0.01). The difference between the egg shell intensity Roman Brown and other varieties is very significant (P0.01). The difference between haelsax brown and other varieties is very significant (P0.01). At the peak of the egg production, Hailan Brown is higher than the other 4 varieties, which are Roma brown, ishaeas, Beijing Red, and haisex brown.25 weeks old. To 43 weeks, the laying rate of sea orchid brown than Roman Brown, isesa brown, Beijing Red and sea Sax Brown is 0.5%, 0.7%, 0.75%, 0.9% respectively. The egg production of hens brown layers is higher than that of sea blue brown 2.08:1, ISA Brown 2.18:1, Roman Brown 2.2:1, sea Sax brown 2.3:1 and Beijing Red 2.4:1.. It is a reference for the breeding of the broad brown layer hens in Shijiazhuang area, and it can also provide a basis for the development of poultry industry.
